Republican challenged by Democrat Troy Jackson in critical Senate race says she opposes Iran war and Canada tariffs

Susan Collins, the Republican senator for Maine, pointedly distanced herself from Donald Trump in a televised debate with Democratic challenger Troy Jackson on Tuesday, as she sought to present an image of independence in a state that has voted against Trump three times.

Proclaiming herself as not the US president’s “favorite senator”, Collins made the highly unusual boast for a Republican that she had voted with Joe Biden, a Democrat, more than 90% of the time when he was president. She also emphasized her differences with her fellow Republicans, saying she voted against her own party more than any other senator.

Baltimore project to be partly funded by US government but owned by defense firm Anduril, founded by Palmer Luckey

Donald Trump on Tuesday announced the opening of a new $6.6bn shipbuilding factory in Baltimore, partly funded by the US government but owned by Anduril Industries, a politically connected defense company.

Trump’s appearance at a currently unused shipyard in Sparrows Point is a boost to Anduril, whose founder, Palmer Luckey, is a major GOP campaign fundraiser. Luckey has hosted campaign fundraisers for at least 20 Republican politicians, including Trump, the Guardian reported in August. He has given $5.9m to Republican causes since 2017.

President floats idea as voter anger over rising costs threatens Republican hopes in November midterms

Donald Trump said on Tuesday his administration was considering suspending the federal gasoline tax, a sign the president is noticing voter anger over fuel costs a month before the midterm elections.

“We’re thinking about that,” Trump said when asked whether the tax should be suspended.

Lawyers tell judge ABC being unfairly targeted as US regulator seeks review of network’s local TV station licenses

Lawyers for Disney accused the Trump administration of “blatant violations of the US constitution” and censorship on Tuesday in the first court hearing over the Federal Communications Commission’s early review of the media giant’s eight local television station licenses.

District judge Loren AliKhan seemed unswayed by government arguments that the order to force Disney’s ABC to apply years early to renew local television station licenses was tied to an investigation into parent company Disney’s hiring practices.

Former and current officials who bolstered claims of voter fraud in 2020 make fresh allegations of vulnerabilities

Prominent election deniers have spent recent weeks stoking fears over US election security before next month’s midterms, echoing claims pushed by Donald Trump to justify asserting more control over voting.

On conservative-friendly media outlets, former or current officials who tried to bolster the US president’s false claims of mass voter fraud in 2020 have in recent weeks made fresh allegations of election vulnerabilities.

Gavin Newsom said state’s threat-assessment center would be on heightened alert after president’s remarks

California’s governor, Gavin Newsom, on Tuesday directed the state’s emergency preparedness center to “actively monitor” possible threats to the state after Donald Trump suggested Iran could “take out” the cities of Los Angeles and San Diego.

Trump has faced a chorus of condemnation from Democratic leaders in California after his comments at a rally in Nebraska on Monday night, which the White House has suggested were being taken out of context.

Having seemingly written off the midterms, the Republican bigwigs are making their pitches for 2028. But the current commander-in-chief could be looking closer to home

The US midterm elections are a month away and it’s looking rough for the Republicans. I wouldn’t discount devious schemes behind the scenes, but, on the face of it, the president and his entourage seem to be flailing. Donald Trump is desperately dangling money in front of voters and promising “a big surprise”. Meanwhile, the vice-president, JD Vance, and the GOP senator Ted Cruz seem more concerned with fighting over who will be Trump’s heir than with the midterms.

If the polls are to be believed, Vance is the frontrunner for the Republican presidential nomination in 2028. But while he may have great name recognition, Vance is also unlikable. According to the CNN analyst Harry Enten, he is one of the least popular vice-presidents in history. He’s also apparently made enemies within his own party, largely because of his scepticism about the Iran war. His detractors include Cruz, who told MS Now in August that Vance wasn’t a shoo-in for the nomination. The party, Cruz said, was still figuring out the best candidate and needed “to decide who we are, what do we believe”.

Officials file ‘denaturalization actions’ against people accused of crimes in what they call ‘largest’ such initiative

Donald Trump’s justice department has moved to strip the citizenship of 40 naturalized citizens accused of crimes in what authorities describe as “the largest” such initiative over a single period during his administration.

US justice department officials on Monday announced the filing of “denaturalization actions” against more than three dozen people alleged to have committed such offenses as “acting as an agent for a foreign government, committing voluntary manslaughter, and aggravated sodomy against a special‑needs man”.

John Murdock had been working for the agency for 18 years and his resignation comes during an exodus of longtime federal workers and scientists

An 18-year veteran of the US Department of the Interior has resigned in protest from the sprawling federal agency, denouncing “a deeply troubling assault on the rule of the law” that took place at the department under Donald Trump.

John Murdock, an attorney and self-described conservative Christian, began working for the agency’s legal office in 2002. In his resignation letter, first sent to his supervisor earlier this year and obtained exclusively by the Guardian and Public Domain, Murdock cites “glaring legal flaws” he witnessed within the agency during the course of the Trump administration, as well as concerns over offshore oil and gas drilling, the aggressive push to expand fossil fuels and the flouting of environmental regulation.

Trump’s counter-terrorism ‘czar’, Sebastian Gorka, was scheduled to speak at conference but White House says he will no longer attend

A National Conservatism (NatCon) conference beginning today in Jerusalem advertises a talk from the Trump administration’s anti-terrorism czar alongside speeches from far-right Israeli politicians, European figures who have faced disciplinary action over alleged antisemitism, and Christian nationalist and far-right figures from the United States.

The Jerusalem event is perhaps the most significant recent gathering to feature large contingents of Israeli nationalists alongside Christian nationalists and far-right European nationalists from a milieu sometimes shadowed by accusations of antisemitism.

The findings come after warnings from tech leaders that AI placed in the wrong hands could trigger larger threats such as nuclear war or bioweaponry destruction

Misusing artificial intelligence (AI) is the top threat to companies’ reputations – more so than being accused of putting children in the way of mental, emotional or physical harm and issues exposed by the US-Israel war on Iran, among other brand risks, according to a new survey of more than 150 public affairs leaders.

Those findings in the new edition of the quarterly Reputation Risk Index, released on Tuesday, came on the heels of other perhaps more dire warnings from leading tech figures that AI in the wrong hands could precipitate existential threats on a mass scale such as nuclear war or destruction by bioweaponry.

LaMonica McIver is only the 15th member of Congress have a baby while serving, and also the only member indicted for visiting ICE facility

A US congresswoman who just gave birth to a baby girl faces a deadline this week on whether to seek a rehearing of a federal case against her by the Trump administration after an oversight visit to an immigration detention facility.

LaMonica McIver, 40, represents New Jersey’s 10th congressional district. She gave birth to her second child last Thursday – a rarity for a sitting member of Congress. She is only the 15th member of Congress to give birth while serving and part of a small subset of congresswomen who have school-age children.

November’s midterms bring parallels with a moment in October 1988. But Pinochet’s exit wasn’t the end of his influence

A malignant, monomaniacal president, deeply unpopular, faces an election that could restrict his power and end his domination of his country.

It is true that, to influence the outcome, he counts on a supine supreme court and his ability to legislate through executive decrees, as well as an onslaught of fake news accusing his opponents of being unpatriotic communists, true that he has colossal financial support from an entrenched oligarchy that has thrived thanks to his rightwing neoliberal policies, true that he has gone out of his way to limit the freedom of those who vote and true that he has absolute command of the armed forces.
